Frédéric Cailliaud (9 June 1787 – 1 May 1869) was a French naturalist, mineralogist and conchologist.
He was born, and died, in Nantes.
He travelled in Egypt, Nubia, and Ethiopia, collecting minerals and making observations.
He was a part of the military expedition that his patron Viceroy Muhammad Ali sent south to conquer the Kingdom of Sennar, but also marched further into Fazogli where Caillaud searched for outcroppings of gold while the commander Ismail, son of Muhammad Ali, enslaved locals and slaughtered all who resisted him.
Although he failed to find any sizeable deposits of gold in the mountains along the modern Sudan-Ethiopia border, he did make a sufficiently detailed survey of the area to be published after he returned to France in 1827.
"Shortly after his return, he published Travels in the Oasis of Thebes, with never-before-seen information on the people and places of the Western Desert.
His Travels to Meroë (mer-oh-ay) not only offered similarly pioneering information on the peoples and regions south of the Nile’s first cataract, but also constituted the first scientific survey of Sudanese monuments.
In addition, he brought back a large corpus of correctly copied textual material that, along with objects in his newly acquired collection, helped the historian Jean-François Champollion decipher the hieroglyphic language of ancient Egypt.
So esteemed were Cailliaud’s contributions to knowledge that in 1824 he was awarded the French Legion of Honor."He was curator of the museum at Nantes from 1836 to 1869.
In addition to his two monumental works on Egypt, Travels in the Oasis of Thebes and Travels to Meroë, and his ample natural history publications, Cailliaud strove to produce an encyclopaedia on ancient and modern Nile civilizations.
While the visual corpus for this material was produced in the 1830s, the supporting text was reworked numerous times right up until Cailliaud's death.
After his passing, the manuscript for the text of this work was lost until the early 2000s.
It has since been recovered, translated, edited, combined with the intended visual material, augmented with supporting chapters and new artwork, and published through AUC Press.
